Outgoing faxes are currently stored in the temporary directory. Depending on the container hosting OSCAR, this directory may get wiped at random. This can cause serious data loss for users.
The storage for outgoing faxes should be configurable and stored in the oscar_mcmaster.properties file.
Temporary storage is used by all outgoing faxes, which is wiped when the container or system deems it necessary. In Tomcat6, this was only wiped on system restart. In Tomcat7, this is wiped when Tomcat7 starts by default.
Steps to Reproduce:
1. Install OSCAR
2. Send an outgoing fax
3. Outgoing fax is stored to the container's temporary directory.
Important data that is being stored for processing should not be stored in a temporary directory.
